SHINGLE.

Application filed April 17, 1925. Serial No. 23,826.

The object of this invention is to provide an improvement in asphalt or composition shingles and particularly with reference to the method of laying and securing the same on a roof in such manner as to minimize the number of nails required to be driven through each shingle, and also to permit adjustability to compensate for expansion and contraction due to changes in tem- 1 perature, and a range of selection in lapping of the shingles 1n laying.

A further object of this invention is to provide an improved nailing strip adapted to be secured to and project from opposite corners of a shingle, the, strips of adjacent shingles in the same row being adapted to overlap and being slotted to receive a nail.

A further object of this invention is to -provide an improved shingle having a hooked metallic clip at its bottom adapted to embrace the overlapping nailing stripsof shingles in an adjacent row and also being slotted to receive a nail extending through said strips, whereby adjacent rows of shingles are interlocked.

A further object of this invention is to provide an improved flexible shingle having its exposed mar ins folded under to provide a stifi'ened and nished edge adapted to hug closely to a roof and prevent raising by action of the elements.

My invention cons sts in the construction,

arrangement and combination of elements hereinafter set forth, pointed out in the claims and illustrated by the'accompanying drawing, in which I Figure 1 is a face showing a plurality of my improved shingles arranged as required for practical use. Figure 2 is a cross-section, on an enlarged scale, on the line 2-2 of Figure 1. Figure 3 is a section on the line 3-3 of Figure 2. Figure 4 is a perspective view showing one of the nailing strips detached. Figure 5 is a perspective view showing one of the hooked bottom clips detached.

Figure 6 is a perspective view showing a modified form of slotted nailing strip.

Figure 7 is a perspective view showing two overlapping nailing strips of further modified form.

Figure 8 is a section similar to Figure 2 showing .a modified form of nailing strip and sliding connection between adjacent shingles in the same row Figure 9 is a perspective view showing one of the looped connecting members employed in the form shown in Figure 8. v r

Fhis invention relates to and is an improvement onthe devices illustrated and described in my application filed October 23, 1923, Serial Number 670,537, to which reference hereby ismade.

The shingles 10 may be of any desired shape or configuration, and the exposed portions are here shown as presenting two curved margins connected at their lower ends by a short straight margin which is in efiect a continuation of the are common to two adjacent curved margins of shingles of the next lower row, as shown in Figure 1. The shingles may be made ofany suitable flexible or partially flexible material, such as waterproofed paper, composition or the like, and preferably are given a coating of substance to render them fireproof in a common manner. The exposed margins of the shingle preferably are formed with a crimped or turned under portion 11 which thickens, strengthens and reinforces such exposed margin, gives it a finished appearance'and causes it-to hug tightly to the roof or shingle assembly when laid so that it cannot be raised by the wind, and prevents the entrance of sleet,'snow or rain. The exposed marginal portion of each shingle pref erably is rolled or crimped inwardly and pressed outwardlpfrom the plane of the shingle, whereby the turned-in margin is in a plane substantially with the body of the shingle, or in other words the inner sur face of the shingle is all in the same plane and all in contact with the underlying surface, as clearly shown in Figs. 2 and 8. Affixed to each lateral corner of each shingle 10 is a sheet metal clip 12, the body of which preferably is rectangular and overlies a portion of the face of the single, at such corner and is suitably secured thereto.- The securing means may be pointed teeth 13 on one or more margins of the clip and a flange or ear 14 on its outer margin adapted to be folded around and'crimped to the margin of the shingle, the teeth 13 being caused to penetrate the shingle and be clenched against the lowei face thereof. These fastening means may be employed selectively or conjunctively, and the number of either may be increased if deemed necessary. Each clip 12 is formed with a tongue or strip 15 extending therefrom and projecting beyond the shingle to which the clip is attached. in this instance near the upper end ot the curved margin of the shingle. and saidtongue or strip is formed with a longitudinal slot 16 adapted to receive a nail 17 or similar fastening means. The slotted strips or tongues 15 of adjacent shingles in the same row are adapted to overlap to greater or less extent. depending upon the amount of lap of said shingles relative to others in the next lower row; and the nail 17. passing through the slotted tongues or strips of adjacent shingles in the same row, tends toprevent up or down movement of said shingles and movement away from the root. but permits some sidewise movement to compensate for expansion and contraction of the material of the shingle due to changes in temperature.

A clip 18 is fixed to the rear face ofthe lower portion of each shingle 10. as by means of pointed teeth 19 adapted to penetrate the shingle. and saidclip is formed with a hook 20 substantially parallel therewith and spaced rearwardlv from the shingle. The

. hook flange 20 is formed with a vertical slot 21. When one row of shingles has been laid by driving nails through their overlapping slotted tongues or strips, another row is snperposedthereon,overlapping upon the first row to the desired extent. The nails 17 are not driven clear home in the sheathing but the strips or tongues are permitted to be spaced somewhat therefrom so that the hook flange of the next succeeding row of shingles may be forced beneath said tongues or strips, as shown in Figure 2, the slot 21 engaging the nail 17 and permitting passage of the hook flange. which are hooked bcneath and around said overlapping strips or tongues and the nails therein b v upward movement of the shingle. This forms an interlocking connection between the successive rows of shingles and holds the lower portions of each row in close contact with those beneath them.

As shown in Figure t. the tongues or strips 12 ma beot' considerable length and may be provided with graduations J2 thereon to guide the workman in laying the shingles and driving the nails in the proper place in the slots 16 to secure the desired lap of shingles when laid.

In Figure 7 l. have shown the tongues or strips 12-" formed with longitudinal slots in having a series of spaced notches in opening from one margin and adapted to receive'selectivel a lug 16" on the other strip. This also guides the workman in laving the shingles to the desired lap, butflittends to prevent lateral sliding movement of one shingle relative to another when they are laid and the nails driven through the slots .of the overlapping shingles.

In the construction according to Figures 8 therefrom and formed with a hole 25 to reccive a nail such as 17. This holds the strips ,and consequently the adjacent corners of the shingles toward the roof but the loose engagement of the strips by the loop permits some relative longitudinal movement as in the manner and. for the purposes previously set forth. a

I claim as my invention 1. In a single formed of flexible material and having metal clips attached to the lateral sides of said shingle, each of said clips being formed with a slotted tongue projecting beyond the margin ot the shingle and adapted to overlap a. similar tongue on an adjacent shingle in the same row and the overlapping slotted tongues adapted to receive a nail. the combination with each shingle ot' a. hooked clip tixcd to the lower portion of said shingle and adapted to be hooked under and embrace the overlapping tongues of shingles in the subjacent row.
